RUSHING-VALVE.

, ESPECIFICATION forming part of Letters Patent No. 363,660, dated May24, 1887.

Application filed March 25, 1886.

To aZZ whom it may concern:

Bc it known that I, TIMOTHY AMolinari, of Boston,in the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Flushing-Valves, of which the lfollowing is aspecification.

This invention relates' to iiushing-valves for Water-closet'tanks, inwhich a stand-pipe is secured to the valve and projects above the sameinto the tank, and permits the water rising in the tank above the upperend of the stand-pipe to overfiow through said pipe and through thevalve and valve-seat. i

It is` the object of the invention to so improve the construction ofdevices of the character mentioned that when the valve is closed thevalve proper will be certain to bear evenly upon its seat, and when thestandpipe to which the valve is secured is released after having beenraised it will fall with certainty and entire freedom, guiding t-hevalve to its seat, and also to prevent the valve from being movedlaterally from its true seat when in its closed position by the actionof the water in the tank on the stand-pipe, thus obviating theseobjections experienced in flushing-val ves as heretofore constructed.

To the foregoing ends my invention consists in the improvementshereinafter fully described, and ysubsequently set forth in the claims.

Of the drawings hereto annexedand forming a part of this specification,Figure l represents a side elevation of a iiushing-valve embodying myinvention. Fig. 2 represents a vertical section of the same, and Fig. 3isa detail representing a slightly-modified form of the ring encirclingthe stand-pipe.

The same letters of reference indicate the same parts' in all the gures.

In the drawings, a represents a raised valveseat, having its base bformed to be inserted, in the usual manner, in the bottom of a watertankand provided with a central water-way, through which the water flowsfrom the tank when the valve c is raised, a suitable outletpipe beingattached to the lower portion of the base b of the valve-Seat in any known manner. The valve c is annular, and is provided with the usualwasher or packing-ring, d, adapted to bear on the raised valveseat a, as

Serial No. 196,496. (No model.)

formed as a rim or collar, having a fiat surface coinciding with theupper surface or edge of the valve seat. As clearly shown in Fig. v2,the base c of the valve is extended laterally beyond the valve-seat c,as also beyond the packing-ring d, for a purpose to be presentlyexplained. The valve has the stand-pipef attached to it, said pipeprojecting upwardly into the tank and passing through the valve, so thatthe water which rises in the tank above the pipef will escape throughthe valve-seat and outlet-pipe. The pipefis provided at its upper endwith a perforated stud, g, to which the chain (not shown) is attached,whereby the stand-pipe and valve are raised.

To guide the valve and stand-pipe in their vertical movements, and toprevent the valve from being removed from its true seat by the actionofthe water in the tank when closed, I provide a frame consisting of tworings, h i, connected at their outer'edges by bars j. The

ring h of the frame is secured to the base of the valve-seat ashortdistance below the valvescat proper, and the upper ring, i, which ismade broader or wider than ring h, extends inwardly and loosely aroundthe stand-pipe.

rlhe form of that portion of ring t' adjacent to the stand-pipe is shownin Fig. l as a narrow collar, k, and in Fig. 3, showing a modiiied formof said ring t', the part adjacent to the standpipe is formed verynarrow and with a rounded surface, the object of which constructions isto give said ring as little bearing as possible on the standpipe, sothat the movements ofthe latter will be attended with the least possiblefriction, and to avoid the possibility of sediment or any foreignsubstance accumulating between the guide-rin g and standpipe, and thusobstructing the free vertical movements of the latter, as wouldotherwise frequently happen.

The valve proper is constructed so as to move vertically with freedomwithin the line or'circle formed by the barsj of the frame, theperiphery of the base c being extended for this purpose out to or nearlyto said bars. By this construction, should the pipe be canted or movedout of a vertical position when it is IOO raised,rit will not bind inringguide il and be held thereby in an elevated position, and when thevalve is closed it cannot be moved laterally from its true seat by theaction of the waterin the tank upon the upper end of the stand-pi pe, asnot infrequently happens in the operation of valves of this kind.Furthermore,the valve, when lowered, will at all times be guided by theaction of the periphery ofthe base e against the bars j to its exactseat. so that the packingring d will have an even bearing throughout onthe raised valve-seat a, which would not be the case if the valve werenot seated with exactness. By making the valve-seat raised in form I amalso enabled to exactly seat the valve with the utmost facility, and bya simple 'fiat packing-ring or washer make a very close or tight valveat a minimum' expenditure of labor and money, as has been shown.

By my improvementthe guidering 7c can be made very narrow, and so as tobear with the least possible surface against the pipe, which, with thebars j ofthe frame, for guiding the valve proper, and the very narrowbearing of the base e of the valve against said bars, obviatcs allliability of the stand-pipe and valve becoming hung77 when raised, andmakes it certain that the valve will at all times, when lowered, beexactly seated, and by making the valve-seat raised in form a very closeor tight valve is obtained by the use of a at packingring of commonconstruction and at little cost. Furthermore,liability of the freevertical movement of the stand-pipe in the guide-ring becomingobstructed by the accumulation therebetween of sediment or any foreignmatter in the water is overcome, as is also the liability of the valvebeing moved laterally from its seat by the wave action of the water inthe tank on the upper end of the stand-pipe, the guide-barsf serving tokeep the valve exactly upon its seat.

I am aware that valves of various forms have been constructed for usessimilar to that for which my improved valve is adapted, and therefore donot broadly claim a valve of the general construction hereinbeforedescribed,

but confine myself to the combinationsset forth in the claims hereuntoappended, which embrace the improvement whereby I am enabled toaccomplish the objects had in view in constructing the invention.

Vhat I claim is- 1. The combination, with the raised valveseat, of thestand-pipe exteriorly unobstructed between its upper and lower ends, ofthe valve secured to the lower end of the standpipe, said valve havingan extended base, e, provided with a narrow periphery, and with a flatsurface opposite to and coinciding with the upper surface of thevalve-seat, the vflat packingring d, adapted to entirely cover thevalveseat, but not extending to the periphery of the base of the valve,and the frame consisting of the two rings h i and the connectingbars j,the ring 7L beingsecured to the base of the valve-seat, and ring t'surrounding the standpipe above the valve and having a very narrowsurfacebearing with which the pipe is adapted to come in contact,whereby the valve may be easily raised from and fall and be guided withease and certainty to its exact seat, and all liability of the pipe andvalve becoming bound and locked in their guidebearings when the valve israised is avoided, as set forth.

2. The combination, with the valve seat a, of the valve provided withthe extended base e, having a narrow periphery, the washerring d, thestand-pipe f, exteriorly unobstructed between its upper and lower endsand secured at the latter end to the valve, valve-seat base b, ring h,secured to valve-seat base I), guide-bars j, adapted to contact with andguide the base 6 in its movements, and narrow ring 7c, adapted tocontact with and guide the pipef in its movements, as set forth.

In testimony whereof I have signed my name to this speciticatiomin thepresence of two subscribing witnesses, this 10th day of March, 1886. vTIMOTHY MOHUGH.
